Please Note: For technical reasons on this site, the GeoGebra files have
been given the extension .zip instead of the standard .ggb
However there is still no need to extract the contents.
Some of these examples are from other personal web sites or sites such as
GeoGebra.
Some have been taken directly, others have been adapted in varying proportions.
Many have been written by Zen Biker Maniac.
In all cases, the author has published the code to be available to all users.
